Benefits of technology

[0011]Embodiments of the present invention provide a battery assembly that can effectively cool a battery with a simple structure.
[0032]According to an exemplary embodiment of the present invention, the battery can be effectively cooled by generating natural convection with a simple structure rather than by equipping an additional fan.
[0033]In addition, since electrical energy is not additionally used for cooling, the use time of the battery is increased so that a driving distance of an electric vehicle can be increased.

Problems solved by technology

If the heat emission is not sufficiently performed, a temperature variation might occur between the respective unit batteries so that the battery module cannot generate a desired amount of power for motor driving.
In addition, when the internal temperature of the battery is increased due to the heat generated from the rechargeable battery, an abnormal reaction may occur therein, and thus charging and discharging performance of the rechargeable battery may be deteriorated and the life-span of the rechargeable battery may be shortened.

Abstract

A battery assembly has a structure that can effectively cool batteries. A battery assembly according to an exemplary embodiment of the present invention includes a housing, a first battery pack in the housing, and a second battery pack in the housing, the second battery pack being spaced from the first battery pack with a first flow path therebetween, wherein a second flow path is between the battery packs and an inner surface of the housing.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of U.S. Provisional Application No. 61 / 358,350 filed on Jun. 24, 2010, in the United States Patent and Trademark Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND[0002]1. Field[0003]Embodiments of the present invention relate to a battery assembly with cooling.[0004]2. Description of Related Art[0005]A rechargeable battery differs from a primary battery in that it is designed to be repeatedly charged and discharged, while the latter typically makes only the irreversible conversion of chemical to electrical energy. Low-capacity rechargeable batteries are used as the power supply for small electronic devices, such as cellular phones, notebook computers and camcorders, while high-capacity rechargeable batteries are used as the power supply for driving motors in hybrid vehicles and the like.[0006]In general, rechargeable batteries include an electr...
